A new study in Biological Psychiatry answers Stress has numerous detrimental effects on the human body. Many of these effects are acutely felt by the sufferer, but many more go 'unseen', one of which is shortening of telomere length. Telomeres are protective caps on the ends of chromosomes and are indicators of aging, as they naturally shorten over time. However, telomeres are also highly susceptible to stress and depression, both of which have repeatedly been linked with premature...

Every cell in the body has chromosomes with so-called telomeres, which are shortened over time and also through lifestyle choices such as smoking and obesity. Researchers have long speculated that the shortening of telomeres increases the risk of heart attack and early death. Now a large-scale population study in Denmark involving nearly 20,000 people shows that there is in fact a direct link, and has also given physicians a future way to test the actual cellular health of a person. In an...

Researchers from the University of Geneva, Switzerland, discover how enzymatic onslaughts at the ends of our chromosomes are countered Researchers from the University of Geneva (UNIGE), Switzerland, have discovered the crucial role of two proteins in developing a cell 'anti-enzyme shield'. This protection system, which operates at the level of molecular 'caps' named telomeres, prevents cells from treating chromosome ends like accidental DNA breaks and 'repairing' them. Joining chromosome...

Chromosome aberrations happen in pairs when it comes to cancer, TAU research finds A healthy genome is characterized by 23 pairs of chromosomes, and even a small change in this structure – such as an extra copy of a single chromosome – can lead to severe physical impairment. So it's no surprise that when it comes to cancer, chromosomal structure is frequently a contributing factor, says Prof. Ron Shamir of the Blavatnik School of Computer Science at Tel Aviv University. Now...

Telomeres, the very ends of chromosomes, become shorter as we age. When a cell divides it first duplicates its DNA and, because the DNA replication machinery fails to get all the way to the end, with each successive cell division a little bit more is missed. New research published in BioMed Central's open access journal Arthritis Research & Therapy shows that cells from osteoarthritic knees have abnormally shortened telomeres and that the percentage of cells with ultra short telomeres...

Longer Telomeres Mean Longer Lifespan

A new study has found a possible predictor of lifespan. According to researchers at the University of Glasgow in England, the link lies in the telomeres that are located on an individual´s DNA. Telomeres are pieces of DNA that are located on the ends of chromosomal strands. They serve the same purpose as aglets on the ends of shoelaces, keeping the chromosome intact and preventing it from losing viable information over the course of a person´s lifetime. According to professor...
